' BERT, surgeon, and CiiAnLns HENRY LAND,

Optician, subjects of the King of Great Britain, residing at Bradford, in the county of York, England, have invented certain inipro venients in Photographic Stands; of which the following is a specification.

" This invention relates to a hotographic stand and its equipment of ease s, retouching desks or light screens, and studio, employed in broinid printing, for enlarging, reducing, or copying photographs, or for artistically lighting and modeling flowers, fruit, or other small still life studies. l

The object of our invention is to manufacture such stand and its e uipinent in a cheap and portable form, to foldup and occupy the minimum of space, be convertible and adaptable 'to the several uses attached to or necessary in the production and finishing of photographs' as" aforesaid. Also when printing or copying photographs, in addition to ascertaming and registering the distance between the source of light or illuminant and the negative,'we are able to ascertain and register the distance between an object placed upon the support or at any point on the stand, and the lens of the camera or similar apparatus fixed upon another part of the stand, and further to enable all focusing movements to be undertaken by the operator from behind the camera. We attain these objects by the apparatus illustrated in the accompanying drawings, in which Fi 'ure' 1 is a plan'view of a photographic stan with our improvements applied. Fig. 2 is a side View of Fig. 1 showing our improved easel secured to folding support and again in. dotted lines with easel adjusted so as to serve as a desk or board. Fig. 8 1s a side view of stand shown at lug. l with easel fixed in a horizontal position upon sai d stand, with our improved folding light screen supporting retouching desk. Fig. 4- is a side view of stand shown at Fig. 1 with portable studio secured at one end of one slide, and

' camera upon the folded support on the other f slide.

Fig. 5 is a plan of Fig. 2. plan of Fig. 3. of Fig. 4.

' Similar-letters of reference refer to similar parts throughout the several views.

Our photographic stand consists of a base frame or slide A carrying the source. of light Fig. 6 is a Fig. 7 is a sectional end view B. Upon. this frame slide two telescopic f nines C, l), each sliding frame is movable towards or away from the center of frame A, and. carries folding supports E, F, atone end of each. frame (.1 l). These frames C D are provided with overlapping parallel bars which slide between the base A and a crossbar Z secured above the middle part of the said. base and carrying the source. of light B. One of the sides of each sliding frame is notched at the top and inarked with a graduaicd scale of inches or distances commencing at the folding frame end of each, and preferably on the sidenearest the operator, see Fig; 1. By this scale the position or distance of the printing frame fronrthe light can be noted and registered.

Small pivoted stops or catches B are provided, pivoting upon 'a portion of the base frame, the one on the right engages with the notches J in the larger or outside frame I), while the one on the left engages with the notches H in the inner frame C, these stops or catches B rigidly hold the said frames C, D, in position when in use.

A printing frame, easel, or the like nay, be secured to one or other of the suppofts-E-,F, either in a vertical, horizontah or inclined po tion, according to the purpose for which is required. Y Upon the opposite sides of the sliding frames to the notched scales II, J, We set out and mark an additional scale L, M, in inches commencing at the folding supports. With the use of this scale it may be calculated and ascertained by deduction from the distance indicated on the notched scale, the distance between an object placed upon the support it or F or at any other position upon the stani l, and the lensof the camera or the like placed upon another part of the stand. This information cannot be ascertained by reference'to the notched scales, as they only indicate the distance of the object from the source of light or the center of the base frame. it is also ad visable' and preferential to accomplish all'iocusing movements from behind the camera, therefore in order to increase the range and focus up to the extreme limit of each sliding frame, we employ a suit able spring detachable handle N, whose cranked. extreinitiesare made to fit within. suitable-recesses or the like formed in one end of the inner sliding frame C and behind plates 0 attached to said frame. The handle 'ning parallel with the same.

N forms an extension of'one end of the slidable frame which permits the said frame to be operated from a'distance. Hitherto to move the said frame beyond the end of the base frame A, the former had to be adjusted from the opposite end or in front of the camera, and this method greatly retarded the operation of focusing. i

As part of the equipment of the aforesaid photographic stand, we employ a suitably constructed easel P adapted to many uses and constructed of the usual rectangular frame with grooved inner edges, one side P of which with the body P is detachable, see dotted lines at Fig. 2. Two stretchers R a suitable distance apart are secured transversely across the-easel at the back. The space S between these stretchers serves as a slot within which are two screwed bolts T projecting from a plate U fitting within a corresponding groove V between the back of easel and thetransverse stretchers, and run- VVhen' the easel-is required in a Vertical position to form a back ground, these bolts project through. corresponding holes in the folding support E or F, and the easel is secured in position by thumbscrews WV. When required as a desk,

-'the aforesaid bolts T project through both support and a cross piece X upon which hinges one end of a quadrangular frame or leg Y, see Fig. 2. The easel is pushed over until the quadrangular frame abuts against the crossbar Z'of-the base frame A. To ob tain the desired angle the sliding frame 0 is moved further-in or out, as required.

- i When employing aretou'ching desk we secure the easel 'P by any approved means in a horizontal posltloli upon one of the sliding frames, see Fig. 3, and make the same serve as a table upon whicliis mounted the retouching desk and light screen. The light screen 1 is portable and mad'e'in two parts, each 'part forming one side and one end ofthe screen, the end portions are hinged to the side portions, and the whole are'seoured by suitablev fasteners: One end of ti screen has an inclined frar'nei within which is mounted the usual retouching des 3, suit able overhanging cloths 4 surroung the said desk and prevent the passage of light at the edges of the picture when the pic' tjpre does not wholly cover the desk.

When it is'desired to artistic-ally light or model fiowers,'fruit, or other-small still life studies, we construct a small stud and fix the same upon one or other of tie sliding frames C, D. In constructing this studio we a I- empioytwoof theaforesaid easel boards P, one we secure 1n manner and by mepns before described in a vertical position, this forms part of the/backof the studio, the second easel board we place upon the sliding frame D in a horizontal positionwith one end abut ting against the vertical easel, and the other erases end resting upon a suitably shaped cross piece D mounted upon the frame 1), this horizontal easel board serves as the lloor oi' the studio. The back has an upper portion 4" fitted to it, this addition is reversible and so shaped that the studio may receive light from either side. llorizontal rods 5 project from this back part through a framework 3 supported by vertical rods 7 from the 11001 of the studio, these horizontal rods 5 are secured in position by thumbscrews S and. serve to support the cloth screens 9 forming the roof and sides of the studio. The camera is fixed upon the other sliding frame C and the focusing done from behindthe camera.

The scale Z upon the stand A is for enlarging purposes, and in order that when the enlarging lantern is centrally situated upon the latter, the distance the lens projects beyond the center or source of light ma y be noted, and said distance deducted when adjusting the sliding frame C for the aforesaid purpose.

What we claim as our invention, and desire to secure by Letters Patent, is

1. In a photographic stand, the combination, with a base, of two telescopic frames provided with overlapping parallel bars sl id able in the said base and n'ojecting-et opposite ends ofit, and supports for photographic apparatus pivoted to the endport-ions of the said frames. l j
